    摘要: A catheter including an elongate body, a first cutting head and a second cutting head both having a blade, where the blades moves relative each other to provide a shearing action for cardiac tissue. The catheter can further include a stent positioned over an inflatable balloon, where the inflatable balloon can deploy the expandable stent over sheared cardiac tissue. The catheter can further be included in a system having a sheath, where at least a part of the catheter resides in the lumen of the sheath. The sheath further includes a cardiac valve and an expandable filter. The sheath can move relative the cardiac valve and the expandable filter to deploy the cardiac valve and at least a portion of the expandable filter proximal the inflatable balloon and the expandable stent.

    摘要: Occluded vasculature such as occluded arterial vasculature can be recanalized using a device that is configured to penetrate an occlusion, while limiting a distance that said penetration structure can extend in order to limit inadvertent vascular damage. The device can include an elongate sheath and a stylet disposed within the elongate sheath. The elongate sheath and the stylet can include, in combination, an engagement section that is configured to limit relative axial movement between the elongate sheath and the stylet.

    摘要: Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

    摘要: An apparatus for promoting hemostasis of a puncture formed in a blood vessel accessible through an incision tract and methods of use thereof. The apparatus includes distal and proximal balloons each having a contracted position and an expanded position, the proximal balloon spaced by a predetermined initial distance from the distal balloon. The apparatus further includes at least one catheter coupling the distal and proximal balloons to a source of pressurized fluid to selectively actuate the distal and proximal balloons between the contracted and expanded positions.
